This paper develops a form of moral actualism that can explain the procreative asymmetry. Along the way, it defends and explains the attractive asymmetry: the claim that although an impermissible option can be self-conditionally permissible, a permissible option cannot be self-conditionally impermissible.

The author argues for a theory of responsibility for outcomes of imposed risk, based on whether it was permissible to impose the risk. When one tries to apply this persuasive model of responsibility for outcomes of risk imposition to procreation, which is a risk imposing act, one finds that it doesn’t match one’s intuitions about responsibility for outcomes of procreative risk. This mismatch exposes a justificatory gap for procreativity, namely, that procreation cannot avail itself of the shared vulnerability to (...) risks and their constraints—to the balance one is forced to strike between one’s interest in being free to impose risks on others and one’s interest in being safe from harm resulting from the risk imposed by others—which serves to justify risk imposition, generally. Whereas most risk impositions involve trade-offs of liberty and security among people who share the vulnerabilities associated with the taking, imposing, or being constrained from imposing risks, procreation involves the introduction of people into that position of vulnerability in the first place. Thus, when one procreates, one imposes risks in the absence of the shared vulnerability that usually serves as a justification for risk imposition. Procreative risks may not be wrongfully imposed, but they aren’t permissibly imposed in a manner fully comparable to other permissibly imposed risks. This makes procreation a unique form of risk imposition, with unique implications for its justification and for one’s responsibility for its outcomes. This insight can help explain several puzzling procreative asymmetries. (shrink)

The Asymmetry in procreative ethics consists of two claims. The first is that it is morally wrong to bring into existence a child who will have an abjectly miserable life; the second is that it is permissible not to bring into existence a child who will enjoy a very happy life. In this paper, I distinguish between two variations of the Asymmetry. The first is the Abstract Asymmetry, the idealized variation of the Asymmetry that many (...) philosophers have been trying to solve. The second is the Real-World Asymmetry, a non-idealized variation that applies explicitly to cases of ordinary human reproduction. I argue that the Real-World Asymmetry can be defended by properly acknowledging the general wrongness of causing someone else to suffer, the limits of what morality can reasonably demand of us, and the significance of respecting women’s autonomy. I then argue that the Abstract Asymmetry is indefensible. (shrink)

Many have offered accounts of the procreative asymmetry, the claim that one has no moral reason to create a life just because it would be happy, but one has moral reason not to create a life just because it would be miserable. I suggest a new approach. Instead of looking at the procreative asymmetry on its own, we can situate it within a broader landscape of asymmetries. Specifically, there are two other analogous asymmetries in the prudential (...) and epistemic domains. The prudential asymmetry says that one has no prudential reason to acquire a desire just because it would be satisfied, but one has prudential reason not to acquire a desire just because it would be frustrated. The epistemic asymmetry says that one has no epistemic reason to acquire a belief just because it is true, but one has epistemic reason not to acquire a belief just because it is false. The existence of these analogous asymmetries in these normative domains suggests the possibility of a unified account of all three asymmetries as instances of a more fundamental asymmetry of value-based reasons. This paper develops a working model of what such a unified account might look like. Such an account can give us a unified explanation of a variety of phenomena, reinforce the plausibility of each of these asymmetries, and give us a novel picture of how value gives us reasons that might extend beyond these three applications.

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing (...) to the idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

According to the Asymmetry, we’ve strong moral reason to prevent miserable lives from coming into existence, but no moral reason to bring happy lives into existence. This procreative asymmetry is often thought to be part of commonsense morality, however theoretically puzzling it might prove to be. I argue that this is a mistake. The Asymmetry is merely prima facie intuitive, and loses its appeal on further reflection. Mature commonsense morality recognizes no fundamental procreative asymmetry. (...) It may recognize some superficially similar theses, but we will see that they derive from more familiar principles, and are compatible with there being moral reason to bring happy lives into existence.

In this article I reconsider David Benatar's primary argument for anti‐natalism—the asymmetry argument—and outline a three‐step process for rejecting it. I begin in Part 2 by reconstructing the asymmetry argument into three main premises. I then turn in Parts 3–5 to explain how each of these premises is in fact false. Finally, I conclude in Part 6 by considering the relationship between the asymmetry argument and the quality of life argument in Benatar's overall case for anti‐natalism and (...) argue that it is the latter argument that is actually doing the work. In this sense, the asymmetry argument is not only unsuccessful in generating Benatar's anti‐natalist conclusion, it is also unnecessary as well. (shrink)

This paper develops transfinite extensions of transitivity and acyclicity in the context of population ethics. They are used to argue that it is better to add good lives, worse to add bad lives, and equally good to add neutral lives, where a life's value is understood as personal value. These conclusions rule out a number of theories of population ethics, feed into an argument for the repugnant conclusion, and allow us to reduce different-number comparisons to same-number ones. Challenges to these (...) arguments are addressed, including the issue of comparing existence and non-existence in terms of personal value, the possibility of minimal quanta of time and life, and the meaningfulness of measuring closeness between outcomes with different population sizes. An asymmetry is uncovered between transfinite cycles of worseness and betterness, supporting a version of the weak procreative asymmetry. Transfinite transitivity principles are also favourably compared to the better-known principles of continuity. (shrink)

Analytic philosophers tend to agree that intentional parental genetic shaping and intentional parental environmental shaping for the same feature are, normatively, on a par. I challenge this view by advancing a novel argument, grounded in the value of fair relationships between parents and children: Parental genetic shaping is morally objectionable because it unjustifiably exacerbates the asymmetry between parent and child with respect to the voluntariness of their entrance into the parent–child relationship. Parental genetic shaping is, for this reason, different (...) from and more objectionable than parental environmental shaping. I introduce a distinction between procreative decisions one makes qua mere procreator—that is, without the intention to rear the resulting child—and procreative decisions one makes qua procreator-and-future childrearer. Genetic shaping is objectionable when undertaken in the latter capacity: Both selection and enhancement are objectionable because they introduce an unnecessary and avoidable inequality in the parent–child relationship; in the case of enhancement, this also results in harm to the future child.

Procreative obligations are often discussed by evaluating only the consequences of reproductive actions or omissions; less attention is paid to the moral role of intentions and attitudes. In this paper, I assess whether intentions and attitudes can contribute to defining our moral obligations with regard to assisted reproductive technologies already available, such as preimplantation genetic diagnosis (PGD), and those that may be available in future, such as reproductive genome editing and ectogenesis, in a way compatible with person‐affecting constraints. I (...) propose the parent–child relationship argument, which is based on the moral distinction between creating and parenting a child. Hence, I first argue that intentions and attitudes can play a role in defining our moral obligations in reproductive decisions involving PGD. Second, I maintain that if we accept this and recognize reproductive genome editing and ectogenesis as person‐affecting procedures, we should be committed to arguing that prospective parents may have moral reasons to prefer reproduction via such techniques than via sexual intercourse. In both cases, I observe an extension of our procreative responsibility beyond what is proposed by the consequentialist person‐affecting morality. (shrink)

Imagine a world where everyone is healthy, intelligent, long living and happy. Intuitively this seems wonderful albeit unrealistic. However, recent scienti c breakthroughs in genetic engineering, namely CRISPR/Cas bring the question into public discourse, how the genetic enhancement of humans should be evaluated morally. In 2001, when preimplantation genetic diagnosis (PGD) and in vitro fertilisation (IVF), enabled parents to select between multiple embryos, Julian Savulescu introduced the principle of procreative bene cence (PPB), stating that parents have the obligations to (...) choose the child that is expected to have the best life. In this paper I argue that accepting the PPB and the consequentialist principle (CP) that two acts with the same consequences are morally on par, commits one to accepting the parental obligation of genetically enhancing one's children.

This book rethinks procreative responsibility considering the continuous development of Assisted Reproductive Technologies. It presents a person-affecting moral argument, highlighting that the potential availability of future Assisted Reproductive Technologies brings out new procreative obligations. Traditionally, Assisted Reproductive Technologies are understood as practices aimed at extending the procreative freedom of prospective parents. However, some scholars argue that they also give rise to new moral constraints. This book builds on this viewpoint by presenting a person-affecting perspective on the impact (...) of current and future Assisted Reproductive Technologies on procreative responsibility, with a specific focus on reproductive Genome Editing and ectogenesis. The author shows that this perspective is defensible both from a consequences-based person-affecting perspective and from a person-affecting account that considers morally relevant intuitions and attitudes. -/- .

Many contemporary ethical debates turn on claims about the nature and extent of our alleged procreative moral rights: moral rights to procreate or not to procreate as we choose. In this article, I argue that there are no procreative moral rights, in that generally we do not have a distinctive moral right to procreate or not to procreate as we choose. However, interference with our procreative choices usually violates our nonprocreative moral rights, such as our moral rights (...) to bodily autonomy or to privacy. My argument presents hypothetical cases in which a state interferes with a person's procreative choices in order to promote aggregate social welfare, but this interference does not violate any of the person's nonprocreative moral rights. These cases not only undermine frequently made claims that widely recognized nonprocreative moral rights entail procreative moral rights, they also challenge the intuitively plausible claim that interference with our procreative choices as such violates our moral rights. What at first appear to be substantive moral rights are in fact a kind of illusion created by the frequent overlap of other rights, but lacking in substance beyond that overlap. While this argument against the existence of procreative moral rights has substantive implications for ongoing debates in reproductive ethics, I ultimately suggest that it is consistent with a progressive approach to reproductive justice.

Pallikkathayil argues that restrictions on abortion are inconsistent with the usual demands that states place on their citizens. States don't require their citizens to make their bodies available for the protection of other people's interests. Yet, when abortion is restricted, women who can be pregnant are less entitled than other citizens to decide on how their bodies are to be used; then, states fail to treat women as equal before the law. The argument is supposed to hold even if one (...) assumes that fetuses at various stages of development are as morally considerable as (already born) children, and even if, moreover, fetuses have passive citizenship status – that is, if they have claims to state protection. Pallikkathayil's argument comes at excessive theoretical costs, rulling out (a) general duties to help others in the protection of vital interests via relatively non‐burdening donation, e.g. of blood, and (b) plausible although demanding special duties of procreative parents. Nevertheless, I agree with Pallikkathayil's conclusion that existing legal restrictions on abortion violate the state's duty to treat its citizens as equal, and are hence illegitimate; namely, because they fail to hold all procreators ‐ whether or not gestational ‐ equally liable.

The argument of Julian Savulescu’s 2001 paper, “Procreative Beneficence: Why We Should Select the Best Children” is flawed in a number of respects. Savulescu confuses reasons with obligations and equivocates between the claim that parents have some reason to want the best for their children and the more radical claim that they are morally obligated to attempt to produce the best child possible. Savulescu offers a prima facie implausible account of parental obligation, as even the best parents typically fail (...) to do everything they think would be best for their children let alone everything that is in fact best for their children. The profound philosophical difficulties which beset the attempt to formulate a plausible account of the best human life constitute a further independent reason to resile from Savulescu’s conclusion. Savulescu’s argument also requires parents to become complicit with racist and homophobic oppression, which is yet another reason to reject it. Removing the equivocation from Savulescu’s argument allows us to see that the assertion of an obligation to choose the “best child” has much more in common with the “old” eugenics than Savulescu acknowledges.

In this conceptual paper, the traditional conceptualization of sustainable entrepreneurship is challenged because of a fundamental tension between processes involved in sustainable development and processes involved in entrepreneurship: the concept of sustainable business models contains a paradox, because sustainability involves the reduction of information asymmetries, whereas entrepreneurship involves enhanced and secured levels of information asymmetries. We therefore propose a new and integrated theory of sustainable entrepreneurship that overcomes this paradox. The basic argument is that environmental problems have to be conceptualized (...) as wicked problems or sustainability-related ecosystem failures. Because all actors involved in the entrepreneurial process are characterized by their epistemic insufficiency regarding the solving of these problems, the role of information in the sustainable entrepreneurial process changes. On the one hand, the reduction of information asymmetries primarily aims to enable actors to become critical of sustainable entrepreneurs’ actual business models. On the other hand, the epistemic insufficiency of sustainable entrepreneurs guarantees that information asymmetries remain as a source of new sustainable business opportunities. Three further characteristics of sustainable entrepreneurs are distinguished: sustainability and entrepreneurship-related risk-taking; sustainability and entrepreneurship-related self-efficacy; and the development of satisficing and open-ended solutions, together with multiple stakeholders.

In her 1993 book Freedom within Reason, Susan Wolf discusses what she identifies as an asymmetry between the good and the bad: to qualify as doing good in a praiseworthy way, it is not necessary that one should have the ability to do otherwise, but in order to qualify as doing something bad in a blameworthy way, it is necessary that one has the ability to do otherwise. In this chapter, I relate this asymmetry between the good and (...) the bad that Wolf discusses to a range of other asymmetries between the good and the bad that various philosophers – both historical figures and contemporary philosophers – have identified. I discuss different ways of thinking about the relations among these supposed asymmetries between the good and the bad, identify different ways in which one can relate to these ideas in one’s philosophical thinking, and lastly also argue that the long history of philosophical reflections on asymmetries between the good and the bad is interesting to contemporary discussions within applied ethics. In particular, I relate these ideas about asymmetries between the good and the bad to contemporary discussions about moral responsibility – and possible gaps in responsibility – within the ethics of artificial intelligence.

We argue for asymmetries between positive and negative partiality. Specifically, we defend four claims: i) there are forms of negative partiality that do not have positive counterparts; ii) the directionality of personal relationships has distinct effects on positive and negative partiality; iii) the extent of the interactions within a relationship affects positive and negative partiality differently; and iv) positive and negative partiality have different scope restrictions. We argue that these asymmetries point to a more fundamental moral principle, which we call (...) Morality’s Harmonious Propensity. According to this principle, morality has a propensity toward preserving positive relationships and dissolving negative ones. (shrink)

In 2019, several US states passed “heartbeat” bills. Should such bills go into effect, they would outlaw abortion once an embryonic heartbeat can be detected, thereby severely limiting an individual’s access to abortion. Many states allow health care professionals to refuse to provide an abortion for reasons of conscience. Yet heartbeat bills do not include a positive conscience clause that would allow health care professionals to provide an abortion for reasons of conscience. I argue that this asymmetry is unjustified. (...) The same criteria that justify protecting conscientious refusals to provide abortion also justify protecting positive conscientious appeals regarding abortion. Thus, if the law provides legal exemptions for health care professionals who, as a matter of conscience, refuse to provide abortions where it is legal, it should also provide exemptions for health care professionals who, as a matter of conscience, feel obligated to provide abortions where it is illegal.

Many philosophers are attracted to a complaints-based theory of the procreation asymmetry, according to which creating a person with a bad life is wrong (all else equal) because that person can complain about your act, whereas declining to create a person who would have a good life is not wrong (all else equal) because that person never exists and so cannot complain about your act. In this paper, I present two problems for such theories: the problem of impairable-life acceptance (...) and an especially acute version of the problem of improvable-life avoidance. I explain how these problems afflict two recent complaints-based theories of the procreation asymmetry, from Joe Horton and Abelard Podgorski. (shrink)

Generic statements (‘Tigers have stripes’) are pervasive and early-emerging modes of generalization with a distinctive linguistic profile. Previous experimental work found that generics display a unique asymmetry between their acceptance conditions and the implications that are typically drawn from them. This paper presents evidence against the hypothesis that only generics display an asymmetry. Correcting for limitations of previous designs, we found a generalized asymmetry effect across generics, various kinds of explicitly quantified statements (‘most’, ‘some’, ‘typically’, ‘usually’), and (...) variations in types of predicated properties (striking vs. neutral). We discuss implications of these results for our understanding of the source of asymmetry effects and whether and in which ways these effects might introduce biased beliefs into social networks.

Herjeet Kaur Marway recently proposed the Principle of Procreative Justice, which says that reproducers have a strong moral obligation to avoid completing race and colour injustices through their selection choices. In this article, we analyze this principle and argue, appealing to a series of counterexamples, that some of the implications of Marway's Principle of Procreative Justice are difficult to accept. This casts doubt on whether the principle should be adopted. Also, we show that there are some more principled (...) worries regarding Marway's idea of a strong pro tanto duty not to complete injustices through one's procreative choices. Nonetheless, we believe Marway's arguments point in the right general direction regarding duties and structural injustice. Thus, in the final part, we suggest a positive proposal on how it would be possible to respond to the cases we raise. More specifically, we explore the suggestion that agents have a pro tanto duty to participate in eliminating structural injustice. Importantly, this duty can be satisfied, not only in procreation choices but in multiple ways. (shrink)

Many people think that the amount of evil and suffering we observe provides important and perhaps decisive evidence against the claim that a loving God created our world. Yet almost nobody worries about the ethics of human procreation. Can these attitudes be consistently maintained? This chapter argues that the most obvious attempts to justify a positive answer fail. The upshot is not that procreation is impermissible, but rather that we should either revise our beliefs about the severity of global arguments (...) from evil or develop new and better defenses of human procreation. Although both possibilities are worthy of pursuit, this chapter focuses on the latter possibility. (shrink)

This paper evaluates Jonathan Quong’s attempt to defend a version of political liberalism from the asymmetry objection. I object that Quong’s defence relies on a premise that has not been adequately supported and does not look as if it can be given adequate support.

The question of whether or not one should procreate is rarely cast as a personal choice in philosophical discourse; rather, it is presented as an ethical choice made against a backdrop of aggregate concerns. But justifications concerning procreation in popular culture regularly engage with the role that identity plays in making procreative decisions; specifically, how one’s decision will affect who they are and who they might be in the future. Women in particular cite the personally transformative aspects of becoming (...) a parent — personal circumstances, including socioeconomic status, age, health, and relationship status — as the most important considerations for the decision they make regarding possible parenthood, and not the more aggregate concerns that an ethics of procreation prioritizes. I highlight women because when women undergo a transformative experience related to parenthood, they do so in contexts where the social, economic, and emotional effects related to pregnancy and motherhood are extensive and impose greater effects on women than men. These harmful material effects threaten a woman’s economic stability, career development, social relationships, and emotional health. Because of this, I argue that an ethics of procreation must engage with the ways in which women’s identities are transformed through procreative decisions. (shrink)

Preconception sex selection for non-medical reasons raises serious moral, legal and social issues. The main concerns include the threat of a sex ratio distortion due to a common preference for boys over girls, the charge of sexism, the danger of reinforcing gender stereotypical behaviour in sex selected children, and the fear of a slippery slope towards creating designer babies. This paper endeavours to show that none of the objections to preconception sex selection is conclusive and that there is no justification (...) for denying parents the right to choose the sex of their prospective children.

Varying degrees of symmetry can exist in a social network's connections. Some early online social networks (OSNs) were predicated on symmetrical connections, such as Facebook 'friendships' where both actors in a 'friendship' have an equal and reciprocal connection. Newer platforms -- Twitter, Instagram, and Facebook's 'Pages' inclusive -- are counterexamples of this, where 'following' another actor (friend, celebrity, business) does not guarantee a reciprocal exchange from the other. -/- This paper argues that the basic asymmetric connections in an OSN leads (...) to emergent asymmetrical behaviour in the OSN's overall influence and connectivity, amongst others. This paper will then draw on empirical examples from popular sites (and prior network research) to illustrate how asymmetric connections can render individuals 'voiceless'. -/- The crux of this paper is an argument from the existentialist viewpoint on how the above asymmetric network properties lead to Sartrean bad faith (Sartre, 1943). Instead of genuine interpersonal connection, one finds varying degrees of pressure to assume the Sartrean 'in-itself' (the en soi) mode-of-being, irregardless of the magnitude of 'followers' one has. -/- Finally, this paper poses an open question: what other philosophical issues does this inherent asymmetry in modern social networking give rise to?

The growing demand for uterus transplantation (UTx) invites continued philosophical evaluation of the function of UTx (and what constitutes its ‘success’), as well as the recipient eligibility for UTx. Currently, UTx caters to partnered, cisgender women of childbearing age looking to get pregnant and give birth to a biogenetically related child. The medical justification for this—the treatment of uterine infertility—explains the primacy of this practice. However, this dominant conceptualization of UTx does not necessarily capture the diverse needs for which both (...) cis‐ and transgender women might take interest in UTx that are not strictly procreative, such as bodily integrity and gender identity reasons. In this paper, I argue that non‐procreative motivations for uterus acquisition ought to be taken seriously as a matter of non‐discrimination and consistency. (shrink)

Is the basic mechanism behind presupposition projection fundamentally asymmetric or symmetric? This is a basic question for the theory of presupposition, which also bears on broader issues concerning the source of asymmetries observed in natural language: are these simply rooted in superficial asymmetries of language use— language use unfolds in time, which we experience as fundamentally asymmetric— or can they be, at least in part, directly referenced in linguistic knowledge and representations? In this paper we aim to make progress on (...) these questions by exploring presupposition projection across conjunction, which has typically been taken as a central piece of evidence that presupposition projection is asymmetric. As a number of authors have recently pointed out, however, whether or not this conclusion is warranted is not clear once we take into account independent issues of redundancy. Building on previous work by Chemla & Schlenker (2012) and Schwarz (2015), we approach this question experimentally by using an inference task which controls for redundancy and presupposition suspension. We find strong evidence for left-to-right filtering across conjunctions, but no evidence for right-to-left filtering, suggesting that, at least as a default, presupposition projection across conjunction is indeed asymmetric.

Peter Godfrey-Smith writes in the section 3.3 “The Ravens Problem” of his book “Theory and Reality” [chapter “Induction and Confirmation”]: “First, the logical empiricists were concerned to deal with the case where generalizations cover an infinite number of instances. In that case, as we see each raven we are not reducing the number of ways in which the hypothesis might fail”. Infinite sets and finite sets have different properties and follow different rules. For example: let’s call “bag X” a specific (...) bag that contains 90 marbles; the generalization A “All marbles in bag X are red” covers a finite number of instances. By contrast, the generalization AE “All things that are not red are not marbles in bag X” covers an infinite number of instances. The propositions A and AE are logically equivalent, but there is an asymmetry due to the fact that A can only have a finite number of instances (since the set of the marbles contained in bag X is a finite set). Because of the aforementioned asymmetry, even though A and AE are logically equivalent propositions, it is wrong to equate an instance of A with an instance of AE. Another example involving a finite set: let’s call “barrique X” a certain 205-liter (54.1553 US gal) barrique. In the following generalization, the expression "all minerals" should not be understood as "all types of minerals", but should be understood literally as "all minerals". B “All minerals are in barrique X”. BE “All objects that are not in barrique X are not minerals”. Of course, a 205-litre barrique cannot contain an infinite number of minerals; the set of objects contained in barrique X is a finite set: therefore in the generalization B we refer to a set that is assumed to be an infinite set (the set of minerals) and to a set (the finite set of minerals contained in barrique X) that is not assumed to be an infinite set. By contrast, in the generalization BE we refer to two sets that are assumed to be infinite sets (the set of all objects that are not contained in barrique X and the set of all objects that are not minerals). Therefore, although B and BE are logically equivalent propositions, an instance of BE cannot be equivalent to an instance of B. Now, let’s analyze the following generalizations. C “All the elements of the set of ravens are elements of the set of black ravens”. CE “All the things that are not elements of the set of black ravens are not elements of the set of ravens”. It is assumed that the number of ravens is infinite, but it is not assumed that the number of black ravens is infinite: that the number of black ravens is infinite is only a hypothesis (for which confirmation is sought), it cannot be assumed as true that the number of black ravens is infinite. Therefore, in the generalization C we refer to a set that is assumed to be an infinite set (the set of ravens) and to a set (the set of black ravens) that is not assumed to be an infinite set. By contrast, in the generalization CE we refer to two sets that are assumed to be infinite sets (the set of all objects that are not elements of the set of black ravens and the set of all objects that are not elements of the set of ravens). Someone could argue that in the generalizations C “All the elements of the set of ravens are elements of the set of black ravens” and CE “All the things that are not elements of the set of black ravens are not elements of the set of ravens” only the set of ravens is assumed to be infinite: but even in this case an asymmetry would remain because C “ All the elements of the set of ravens are elements of the set of black ravens” refers to a set (the set of ravens) that is assumed to be an infinite set and to a set (the set of black ravens) that is not assumed to be infinite; by contrast, CE “All the things that are not elements of the set of black ravens are not elements of the set of ravens” in this case would refer to two sets that are not assumed to be infinite sets. Because of the aforementioned asymmetries, an instance of C cannot be equivalent to an instance of CE. -/- -/- . (shrink)

An explanation of our seeming inability to influence the past.

Empirical evidence shows that people have multiple time-biases. One is near-bias; another is future-bias. Philosophical theorising about these biases often proceeds on two assumptions. First, that the two biases are _independent_: that they are explained by different factors (the independence assumption). Second, that there is a normative asymmetry between the two biases: one is rationally impermissible (near-bias) and the other rationally permissible (future-bias). The former assumption at least partly feeds into the latter: if the two biases were not explained (...) by different factors, then it would be less plausible that their normative statuses differ. This paper investigates the independence assumption and finds it unwarranted. In light of this, we argue, there is reason to question the normative asymmetry assumption. (shrink)

Benatar’s central argument for antinatalism develops an asymmetry between the pain and pleasure in a potential life. I am going to present an alternative route to the antinatalist conclusion. I argue that duties require victims and that as a result there is no duty to create the pleasures contained within a prospective life but a duty not to create any of its sufferings. My argument can supplement Benatar’s, but it also enjoys some advantages: it achieves a better fit with (...) our intuitions; it does not require us to acknowledge that life is a harm, or that a world devoid of life is a good thing; and it is easy to see why it does not have any pro-mortalist implications.

Explanation is asymmetric: if A explains B, then B does not explain A. Tradition- ally, the asymmetry of explanation was thought to favor causal accounts of explanation over their rivals, such as those that take explanations to be inferences. In this paper, we develop a new inferential approach to explanation that outperforms causal approaches in accounting for the asymmetry of explanation.

In a recent book and an article, Carl Craver construes the relations between different levels of a mechanism, which he also refers to as constitutive relations, in terms of mutual manipulability (MM). Interpreted metaphysically, MM implies that inter-level relations are symmetrical. MM thus violates one of the main desiderata of scientific explanation, namely explanatory asymmetry. Parts of Craver’s writings suggest a metaphysical interpretation of MM, and Craver explicitly commits to constitutive relationships being symmetrical. The paper furthermore explores the option (...) of interpreting MM epistemologically, as a means for individuating mechanisms. It is argued that MM then is redundant. MM should therefore better be abandoned. (shrink)

One of the most striking features of causation is that causes typically precede their effects – the causal arrow is strongly aligned with the temporal arrow. Why should this be so? We offer an opinionated guide to this problem, and to the solutions currently on offer. We conclude that the most promising strategy is to begin with the de facto asymmetry of human deliberation, characterised in epistemic terms, and to build out from there. More than any rival, this subjectivist (...) approach promises to demystify the asymmetry, temporal orientation, and deliberative relevance of causal judgements. (shrink)

Sometimes it is not one’s place to blame or forgive. This phenomenon is captured under the philosophical notion of standing. However, there is an asymmetry to be explained here. One can successfully blame, even if one lacks the standing to do so. Yet, one cannot successfully forgive if one lacks the standing to do so. In this article we explain this asymmetry. We argue that a complete explanation depends on not only a difference in the natures of the (...) standing to blame and forgive but also a difference in the natures of blame and forgiveness themselves.

According to the Asymmetry, creating a miserable person is wrong but failing to create a happy person is permissible, other things being equal. Some attempt to underwrite the Asymmetry by appealing to a choice-dependent moral theory according to which the deontic status of an act depends on whether it is chosen by the agent. We show that all choice-dependent moral theories in the literature are vulnerable to what we call the Parent Trap. These theories imply that the presence (...) of impermissible options can generate a moral requirement to create happy people, even at the cost of the procreator’s well-being. We consider two new choice-dependent theories that avoid this result, but show that they generate implausible moral permissions to create miserable people. Either way, choice-dependent theories fail to do justice to the intuitions that motivate the Asymmetry. (shrink)

Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. I propose a unified 'Humean' solution to the two problems. Humeanism allows us to incorporate the Past Hypothesis and the Statistical Postulate into the best system, which we then use to simplify the quantum state of the universe. This enables us to confer the nomological status to the quantum state in (...) a way that adds no significant complexity to the best system and solves the ''supervenient-kind problem'' facing the original version of the Past Hypothesis. We call the resultant theory the Humean unification. It provides a unified explanation of time asymmetry and quantum entanglement. On this theory, what gives rise to time's arrow is also responsible for quantum phenomena. The new theory has a separable mosaic, a best system that is simple and non-vague, less tension between quantum mechanics and special relativity, and a higher degree of theoretical and dynamical unity. The Humean unification leads to new insights that can be useful to Humeans and non-Humeans alike. (shrink)

In some cases, there appears to be an asymmetry in the evidential value of statistical and more individualized evidence. For example, while I may accept that Alex is guilty based on eyewitness testimony that is 80% likely to be accurate, it does not seem permissible to do so based on the fact that 80% of a group that Alex is a member of are guilty. In this paper I suggest that rather than reflecting a deep defect in statistical evidence, (...) this asymmetry might arise from a general constraint on rational inquiry. Plausibly the degree of evidential support needed to justify taking a proposition to be true depends on the stakes of error. While relying on statistical evidence plausibly raises the stakes by introducing new kinds of risk to members of the reference class, paradigmatically `individualized' evidence---evidence tracing back to A's voluntary behavior---can lower the stakes. The net result explains the apparent evidential asymmetry without positing a deep difference in the brute justificatory power of different types of evidence. (shrink)

Numerous philosophers have tried to define modesty, but none of them succeeds in articulating the necessary and sufficient conditions for this virtue. Moreover, all existing accounts ignore the striking self-other asymmetry that is at the heart of modesty. Drawing on the analogy with the practice of giving presents, I clarify and further investigate this self-other asymmetry. In the process, I show why Bernard Williams is right in pointing out the notorious truth that a modest person does not act (...) under the title of modesty and why Alan Bennett is wrong in supposing that all modesty is false modesty.

It is widely held that there is an asymmetry between our access to our minds and our access to others’ minds. Philosophers in the literature tend to focus on the asymmetry between our access to our mental states and our access to those mental states of others that are not shared by us. What if a mental state can have multiple subjects? Is there still an asymmetry between our access to our mental states and our access to (...) those mental states of others that are also ours? In this paper, I discuss the implications of a case of shared consciousness—the case of the Hogan twins—for asymmetry. I start by clarifying the notion of asymmetry. Here I develop a characterization of asymmetry and argue that it is preferable to the standard approaches in the literature. I then present the twins’ case and argue that it does not threaten asymmetry. I close by drawing some lessons. (shrink)

This paper suggests that there are three kinds of meaning: Everyday, Cosmic, and Ultimate. Everyday meaning refers to the value and significance in our everyday lives, including values such as beauty, morality, and truth, and the significance of engagement with them. Cosmic meaning refers to our meaningful role in the cosmos: to the significance and value of our cosmic niche, to the purposes of the cosmos and our place in it. Ultimate meaning is the end-regarding justifying reason, the valued end, (...) or the point of leading a life at all. It is here argued that procreating can be a deep source of Everyday meaning, and perhaps Cosmic meaning. But nothing can provide us with Ultimate meaning. The implications this may have for procreative ethics is considered. (shrink)

Children conceived in order to donate biological material to save the life of an already existing child are known as 'saviour siblings'. The primary reasons that have been offered against the practice are: (i) creating a saviour sibling has negative impacts on the created child and (ii) creating a saviour child represents a wrongful procreative motivation of the parents. In this paper we examine to what extent the creation of saviour siblings actually presents a special case in procreative (...) ethics. Although we do not deny that there is a unique feature present in the saviour sibling case—namely, that the child was created to save their sibling’s life, we argue that the distinctive feature of being a saviour sibling does not make the procreative act wrong. Our claim is that the features that would make the creation of a particular saviour sibling (im)permissible are the same features that would make the creation of any child (im)permissible. Our conclusion is that saviour siblings—in relation to the reasons for the (im)permissibility of their creation—are not a special case for procreative ethics. (shrink)

[This papers explores a novel case for the normativity of knowledge for belief – something that is compatible with the knowledge/factual awareness distinction I've explored elsewhere.] There are two different kinds of enkratic principles for belief: evidential enkratic principles and normative enkratic principles. It’s frequently taken for granted that there’s not an important difference between them. But evidential enkratic principles are undermined by considerations that gain no traction at all against their normative counterparts. The idea that such an asymmetry (...) exists between evidential and normative enkratic principles is surprising all on its own. It is also something that calls out for explanation. Similarly, the considerations that undermine evidential enkratic principles also undermine certain narrow-scope evidential principles. This too generates explanatory questions. I show how a knowledge-first view of rationality can easily address these explanatory questions. Thus we have one more reason to put knowledge first in [some areas of] epistemology. (shrink)

Generic statements (‘Tigers have stripes’) are pervasive and developmentally early-emerging modes of generalization with a distinctive linguistic profile. Previous experimental work suggests that generics display a unique asymmetry between the prevalence levels required to accept them and the prevalence levels typically implied by their use. This asymmetry effect is thought to have serious social consequences: if speakers use socially problematic generics based on prevalence levels that are systematically lower than what is typically inferred by their recipients, then using (...) generics will likely exacerbate social stereotypes and biases. This paper presents evidence against the popular hypothesis that this asymmetry effect is unique to generics. Correcting for various shortcomings of previous studies, we found a generalized asymmetry effect across generics and various kinds of explicitly quantified statements (‘most’, ‘some’, ‘typically’, ‘usually’). In addition, to better understand the conditions under which generalized asymmetry effects may exacerbate biases, we examine whether speakers choose generalizing sentences based simply on their acceptance conditions, or are systematically sensitive to the implications likely drawn by their typical recipients. In support of the latter view, we found that, in neutral or cooperative scenarios, speakers reliably choose generalizing sentences whose implied prevalence levels closely match the actual ones. In non-cooperative scenarios, speakers exploit asymmetry effects to further their own goals by choosing generalizing sentences that are strictly true but likely to mislead their recipients. These results refine our understanding of the source of asymmetry effects and the conditions under which they may introduce biased beliefs into social networks. (shrink)

This contribution explores disability rights protection in Inter-American States within the framework of the OAS and in the context of the obligations established under the CIADDIS and the CRPD. Following the classical division between ‘primary’ and ‘secondary’ rules,3 the contribution first sketches key regulatory initiatives in the area of disability rights and second considers compliance and enforcement mechanisms. Along these lines, the first section illustrates similarities and differences between the CIADDIS and the CRPD and, within this framework, essential regional regulatory (...) initiatives. The second section assesses disability rights in select countries, based on periodic reports under the CIADDIS and CRPD. The section examines the four largest countries by population in the region, notably, the United States of America (‘US’), Mexico, Brazil and Colombia.4 The third section explores the enforcement of disability rights via key cases before the Inter-American Commission on Human Rights (‘IAComHR’) and the Inter-American Court of Human Rights (‘IACtHR’). The purpose is to provideing a comprehensive understanding of disability rights in the region and identifying key regulatory problems and ways forward. (shrink)

The Procreation Asymmetry holds that we have strong moral reasons not to create miserable people for their own sakes, but no moral reasons to create happy people for their own sakes. To defend this conjunction against an argument that it leads to inconsistency, I show how recognizing ‘creation’ as a temporally extended process allows us to revise the conjuncts in a way that preserves their intuitive force. This defense of the Procreation Asymmetry is preferable to others because it (...) does not require us to take on controversial metaphysical or metaethical commitments – in other words, it has the theoretical virtue of portability.

Future-bias is the preference, all else being equal, for positive states of affairs to be located in the future not the past, and for negative states of affairs to be located in the past not the future. Three explanations for future-bias have been posited: the temporal metaphysics explanation, the practical irrelevance explanation, and the three mechanisms explanation. Understanding what explains future-bias is important not only for better understanding the phenomenon itself, but also because many philosophers think that which explanation is (...) the correct one has implications for our evaluation of the normative status of future-bias. In this paper we focus on the connection between future-bias and the temporal value asymmetry. The latter refers to the fact that people tend to assign more value to a state of affairs when it is located in the future, as opposed to being equidistant in the past. All three candidate explanations offered for future-bias proceed by explaining the temporal value asymmetry, and then supposing that future-bias is simply a manifestation of that asymmetry. Recently, however, it has been argued that the conditions under which people display the temporal value asymmetry and future-bias are different, and that this is reason to doubt that the latter is a manifestation of the former. In this paper we empirically test one response to this argument against the manifestation thesis—the simulation response—according to which once we control for the degree to which people can simulate the object of their preference, we find that people display future-bias and the temporal value asymmetry in the same conditions. We find no evidence in favour of the simulation response. Moreover, our results support some previous research that suggests that the temporal value asymmetry is less robust than previously thought, and this in itself casts doubt on the idea that future bias is just a manifestation of this asymmetry.
